Lara Logan: 'We were wrong' on Benghazi

"60 Minutes" correspondent Lara Logan apologized on Friday for her report on Benghazi following new revelations about Dylan Davies, the man who claimed to have been a witness to the attack.

“We were wrong,” Logan told "CBS This Morning."

The veracity of Davies' claim came into question after reports emerged that he had given different accounts to the FBI than he did to “60 Minutes” about where he was the night of the attack on the diplomatic compound.

“We take the vetting of sources and stories very seriously at "60 Minutes," and we took it seriously in this case. But we were misled and we were wrong, and that’s the important thing,” Logan said, adding, “We have to set the record straight and take responsibility.”

Logan said "60 Minutes" did not know of the Blue Mountain incident report until the Washington Post reported on it last week. When they confronted Davies, Logan said he denied the report and said the FBI report would corroborate the version he gave "60 Minutes."
